The Disaster Artist is the book written by Greg Sestero about the making of the worst movie ever made, The Room. It was later made into a movie starring James Franco and Seth Rogen.

2003's The Room is the movie made my Tommy Wiseau and Greg Sestero, two roommates who met in an acting class and became friends. Wiseau decided to write, direct, and star in their own movie with Sestero. The resulting movie is widely considered the worst movie ever made.

And if you haven't seen The Disaster Artist, you should -- it's really good...and bad at the same time. James Franco does an amazing job as Tommy Wiseau, possibly the worst actor ever.

Here's the actual trailer for the original movie.

Watch some of the film's "highlights" to get a taste of how bad it really is. Remember: this movie, with all of these horrible scenes and lines and acting, was actually made and released in a couple of theaters. And it's still watched today by people trying to be ironic.

Now watch a simple synopsis on why this movie is so bad, in case you didn't already know.
